I have just done a 18.104.22.168 installation as my server only supports this version. All setup OK. Problem is when adding allowed currencies. My Base Currency is GBP same as Default Display Currency. When I choose an allowed Currency option like Euro, and click Save, I get the error
GBP is highlighted in allowed currencies. It thinks I am trying to add the same currency again (GBP) as an allowed currency but I am choosing Euro.
Any help greatly appreciated.
You should select adn save the allowed currencies first and then select the euro.
I've just tested with a vanilla installation and works properly.
